The Wale-pieces 3 are provided to securely hold the upper portions of the piles 2 inposition- These Wale-pieces are secured toithe piles 2 by any suitable means as by bolts, nails 'or the like. The Wale-pieces 3 are horizontally disposed and located on both sides of the piles 2. Any desired number of Wale-pieces may be used and may be spaced Af er the ale-pieces apart any distance to insure the .proper strengthening 'ofthe structure. These Walepieces are attached to the poles with overlapped joints, these joints beingstaggered and lapped as clearly shown in Fig. l of the drawings. It will be seen that the construction of; this dike and the location and posi- .tioning of the wale pieces'provide the slid.-
